Any worse than Nokia?
I hope not, if only for the potential that QNX will bring to an increase in Qt development.
The general public will never get a true picture from Nokia, regarding the success of the N9 in termsof numbers sold.
I would put money on the fact that the team at Jolla know, and the decision to continue development of a MeeGo/Mer based device, is based in part, on expected sales, driven by the knowledge of just how successful the N9 was (even from the limited markets in which it was sold) and given the great reviews it received on release.
